Use bluetooth low energy (BLE) technology to track field equipment current location and how equipment was utilized over time.
If your equipment and tools are routinely used in the miltiple field locations, are transferred between job sites and employees, it is not an easy task to keep track of the equipment with the traditional methods. Pen and paper, spreadsheets, and even a desktop software is not very helpful in tracking field equipment. Mobile devices (smartphones or tablets) linked to the cloud software are a good choice for the task. Mobile phones can easily fit into your employees pockets and be carried around, and most of your employees have their own smartphones - so you do not have to spend money on purchasing additional asset tracking hardware. All asset tracking information is sent from the mobile devices to the cloud in real time, so current assets information is available to all authorized employees.
Depending on your preferences and budget, you can use QR codes - in this case asset location is sent to the server only when an employee scans the tag, or you can use bluetooth low energy beacon tags. If you attach BLE beacon tags to the field equipment GPS location of the equipment is sent to the server continuously and automatically, as long as a field technician who is working or relocating equipment has a smartphone in his pocket with the mobile application running in the background. In this case a smartphone is used as an IoT gateway, transfering data from BLE beacon tags to the cloud. You get real time assets and tools location, who is using equipment, and historic equipment usage log.
